Thread: Can leg muscle recovery stimulate further recovery?

  1. #1

    Can leg muscle recovery stimulate further recovery?

    I was looking at Project Walk's site, under the page The First Year Post-Injury, item #10: "If you are not stimulating your lower body, you will not regain function or use of it."

    I was intrigued by the description of how recovery sometimes takes place. According to the description, as the leg muscles gain strength, more is demanded of muscles above and below the pelvis. This stimulates the hip muscles, and recovery may occur upwards -- lower back, abs, and rest of upper body.

    What do you think of this theory? Also, have you ever heard of anyone recovery use of quadriceps first before toe wiggling?

    Thanks.

    I think the Project Walk site, while meaning well and does great for people, is sometimes biased towards their own business. I regained motor function of my right leg three months after my injury and I wasn't in heavy therapy because I was still healing from major surgery and an open incision.

    The information posted on the Project Walk site seems to be representative of their observations and theories. Some of their assertions appeal to "common sense." We see a lot of people that are benefitting from Project Walk, peppered on their website and on this one.

    Yet, overwhelmingly, it seems like if you can't succeed it's because you're not trying hard enough/long enough.

    In our years of experience, we have seen clients with the potential to recover, fail, while others with more severe injuries succeed. The difference between these people is how they each approached the process of recovery. The people who failed set deadlines while the successful thought of recovery as a lifelong journey.
    I'm very much interested in hearing from people who may have benefitted from Project Walk from exercise perspective, but not much in the areas of returns.

    Project Walk has never said that spontaneous recovery of function does not occur after injury. It is a medically proven fact that it does. The big question is when do you decide that you are no longer recovering function? The old medical paradigm was that whatever you recovered in the first 2 years is what you would have for the rest of your life. Dr. John McDonald, Project Walk, and other exercise based programs have shown the world that recovery can occur well after that 2 year mark when exercise is introduced. We believe that the sooner you go after regaining function through exercise, the better chance you will have of recovering significant function.

    Research studies are beginning to show that exercise leads to a spike in the levels of neurotrophins within the spinal cord. Neurotrophins are the builders and caretakers of the nervous system. After an injury they are downregulated (levels are depressed), and through exercise we may be able to upregulate them to a level above what they were pre-injury. Would you rather have this happen as soon as possible after your injury or wait for a year or two?


    A couple of studies:

    Exercise-induced gene expression changes in the rat spinal cord.

    There is growing evidence that exercise benefits recovery of neuromuscular function from spinal cord injury (SCI). However, the effect of exercise on gene expression in the spinal cord is poorly understood. We used oligonucleotide microarrays to compare thoracic and lumbar regions of spinal cord of either exercising (voluntary wheel running for 21 days) or sedentary rats. The expression data were filtered using statistical tests for significance, and K-means clustering was then used to segregate lists of significantly changed genes into sets based upon expression patterns across all experimental groups. Levels of brain-derived neurotrophic factor (BDNF) protein were also measured after voluntary exercise, across different regions of the spinal cord. BDNF mRNA increased with voluntary exercise, as has been previously shown for other forms of exercise, contributed to by increases in both exon I and exon III. The exercise-induced gene expression changes identified by microarray analysis are consistent with increases in pathways promoting neuronal health, signaling, remodeling, cellular transport, and development of oligodendrocytes. Taken together these data suggest cellular pathways through which exercise may promote recovery in the SCI population.

    Exercise restores levels of neurotrophins and synaptic plasticity following spinal cord injury.

    We have conducted studies to determine the potential of exercise to benefit the injured spinal cord using neurotrophins. Adult rats were randomly assigned to one of three groups: (1) intact control (Con); (2) sedentary, hemisected at a mid-thoracic level (Sed-Hx), or (3) exercised, hemisected (Ex-Hx). One week after surgery, the Ex-Hx rats were exposed to voluntary running wheels for 3, 7, or 28 days. BDNF mRNA levels on the lesioned side of the spinal cord lumbar region of Sed-Hx rats were approximately 80% of Con values at all time points and BDNF protein levels were approximately 40% of Con at 28 days. Exercise compensated for the reductions in BDNF after hemisection, such that BDNF mRNA levels in the Ex-Hx rats were similar to Con after 3 days and higher than Con after 7 (17%) and 28 (27%) days of exercise. After 28 days of exercise, BDNF protein levels were 33% higher in Ex-Hx than Con rats and were highly correlated (r=0.86) to running distance. The levels of the downstream effectors for the action of BDNF on synaptic plasticity synapsin I and CREB were lower in Sed-Hx than Con rats at all time points. Synapsin I mRNA and protein levels were higher in Ex-Hx rats than Sed-Hx rats and similar to Con rats at 28 days. CREB mRNA values were higher in Ex-Hx than Sed-Hx rats at all time points. Hemisection had no significant effects on the levels of NT-3 mRNA or protein; however, voluntary exercise resulted in an increase in NT-3 mRNA levels after 28 days (145%). These results are consistent with the concept that synaptic pathways under the regulatory role of BDNF induced by exercise can play a role in facilitating recovery of locomotion following spinal cord injury.

    Dan...I think you are taking that particular quote out of context. That statement I believe is in reference to people giving up their life somewhere else to come here and think and do Project walk 24/7. Our experience has shown that these people may begin to see functional return but by the time it happens they are burnt out and just want to return home. That is one reason we developed the Home Based program and the Train Your Trainer program, so people could get the some of the benefits of our program without having to move here.

    The successful people are the ones who devote several hours a week to exercise but have a life to pursue outside of PW/exercise.

    Eric,

    Of course I understand that it's important to develop a lifestyle of exercise-based-recovery for the best chances of success. I'm hearing a lot of good things about your program, but certainly with SCI nothing is for certain. Are there people who are not accepted into your program? Are there people that Project Walk would not be appropriate for?

    Eric,

    Project Walk is important because I've noticed how much stronger my right leg is just from exercising it and this is eight years post-injury.

    Dan has some very impotant questions. Also, do most insurance companies provide payment for your clients or do most pay out of pocket?

    Those questions are answered in that link.
    Some do, some don't depends on the insurer. Many of our clients are paying out of pocket, however this "pocket" does include trust funds (most set up specifically to pay for PW).
